The study of High School Geometry is largely about understanding the attributes of different terms and rules. In this workbook, students have the opportunity to creatively describe those attributes... More > using the "Pattern Puzzle" approach inspired by the work of Russian computer scientist, Mikhail Bongard. His Bongard Problems described situations by displaying six figures that all contained a common attribute along with six accompanying figures, none of which contained that defining attrribute.
Students can use this principle to describe Geometry terms, theorems, postulates, constructions, properties and laws in ways that will be meaningful to them.
The workbook allows instructors to adapt the content to the particular needs of their own course, and is aligned with the Common Core State Standards for Mathematics.
